Features

Leading drive performance
- The enhanced Real sensorless vector control and vector control achieves improved speed response and high-speed operation.
- The PM motor auto tuning function enables operation of other manufacturers' permanent magnet (PM) motors.

Security & safety
- Controls with safety functions can be easily performed.
(Safety stop function)
- 24 VDC control power input is equipped as standard.
The parameter setting and communication operation can be done without turning ON the main power.
- The operating status immediately before the protective function is activated can be stored with the trace function‚ facilitating the trouble analysis at a separate location by using a USB memory device and the inverter setup software (FR Configurator2).

Easy setup & easy to use
- A USB host connecter (A type) is equipped.
Parameters can be copied to commercial USB memory devices.
- Highly reliable and easily wired spring clamp terminals have been adopted for control circuit terminals.
- Parameter setting mode can be changed to the group parameter mode‚ which provides intuitive and simple parameter settings.
(The conventional parameter setting mode is selected by default.)

Eco-friendly factories
- With Optimum excitation control‚ the excitation current is constantly adjusted to drive the motor in the most efficient method which leads to energy saving.
- The 315K or higher models are inverter-converter separated types‚ which are suitable for power regeneration.
Select the FR-CC2 converter unit according to the connected motor capacity (refer to page 20).

System support
- Rated current and four different overload capacity ratings (SLD rating‚ LD rating‚ ND rating‚ and HD rating) can be selected with parameters.
(Multiple rating)
- Parameters and setting frequency can be changed at the program‚ and the inverter control based on the machine specifications is possible by the PLC function.

Environmental adaptability
- A built-in noise filter (EMC filter)‚ the newly developed drive technology‚ and the power supply technology minimize the EMI emitted from inverters.
- For the 400V class‚ compliance with various countries ship classifications allows use on ship equipment.
